Authorized persons must also follow general and regional installation and safety regulations regarding working with high voltages as well as relevant regulations for the correct use of tools and protective equipment. The SED2 must be grounded (per IEC 536, Class 1, NEC and other relevant industry standards). Extremely hazardous conditions may result if the SED2 is not correctly grounded. NOTE: IP20 and NEMA Type 1 SED2s can operate in ungrounded systems if the Y capacitor is disconnected or removed. IP54, NEMA Type 12 SED2s cannot operate in ungrounded systems. See the Operation in Ungrounded Systems section for more details. The SED2 is suitable for use in a circuit capable of delivering not more than 10,000 symmetrical amperes, for a maximum voltage of 240/480/575V when protected by a time delay Type J, H, or K fuse or circuit breaker. Always wait 5 minutes after disconnecting the SED2 from the power source before performing any work. The DC link capacitors of all SED2s remain charged with dangerous voltages for 5 minutes after all power sources have been disconnected. When working on IP20 units, note that live parts are exposed. Do not touch these parts. In cases where a fault in the input or output power wiring could cause significant equipment damage or severe physical injury (such as potentially dangerous short circuits), use additional external precautions to ensure safe operation (such as independent limit switches and mechanical interlocks). 22 Siemens Building Technologies, Inc.

33 Electrical Installation Extended Storage: Conditioning of Capacitors After an extended period of storage, recharge the capacitors in the SED2. Calculate the storage time from the date of manufacture or the date code, and not from the date of delivery. (See the Interpretation of Serial Numbers and Date Codes section for more details.) The recharge procedure varies according to the storage period as follows: Period of Storage Required Action Total Preparation Time 1 year or less Recharging not required. No preparation 1 to 2 years Before issuing the run command, connect the SED2 to input power for one hour. 2 to 3 years Use a variable AC power source as follows: Apply 25% of the input voltage for 30 minutes. Increase the voltage to 50% for an additional 30 minutes. Increase the voltage to 75% for an additional 30 minutes. Increase the voltage to 100% for an additional 30 minutes. The SED2 is then ready for operation. 1 hour 2 hours 3 or more years Use a variable AC power source as follows: Apply 25% of the input voltage for 2 hours. Increase the voltage to 50% for an additional 2 hours. Increase the voltage to 75% for an additional 2 hours. Increase the voltage to 100% for an additional 2 hours. The SED2 is then ready for operation. CAUTION: 8 hours After an extended period of storage, if capacitors are not properly recharged, catastrophic damage to the drive can result. Siemens Building Technologies, Inc. 23

34 SED2 VFD Startup, Operation, and Maintenance Manual Input Power and Motor Connections DANGER: Make certain that the motor rated full load amps (FLA) does NOT exceed the rated output current of the SED2 controlling it. When multiple motors are simultaneously operated by the SED2, the sum of all motor rated FLA values must be less than or equal to the SED2 controlling them. Never switch on the SED2 with it open. Always isolate the input power cables before connecting them to the SED2. Always use insulated tools when working on input power and motor terminals. Ensure that terminal covers are securely replaced after connecting the input power and motor cables. WARNING: Verify that the SED2 and motor are correctly rated for the input power voltage. Verify that the input power cables are correctly sized for the anticipated use. Confirm that appropriate circuit breakers or fuses have been installed between the input power supply and the SED2. Never use high-voltage insulation test equipment on any cables connected to the SED2. 24 Siemens Building Technologies, Inc.

35 Electrical Installation Operation in Ungrounded Systems IP20 and NEMA Type 1 SED2s can operate in ungrounded systems if the Y capacitor is disconnected or removed. They remain in operation when an input ground fault occurs. In the event of an output ground fault, the SED2 switches off and displays fault code F0001. NOTE: IP54, NEMA Type 12 SED2s cannot operate in ungrounded systems. Ungrounded Systems and Y Capacitor In ungrounded systems, remove or disconnect the Y capacitor (and install an output choke/load reactor) per Figures 8 through VFD060R1 Figure 8.

47 Electrical Installation Input Power Connection DANGER: As supplied, the SED2 must be grounded (per IEC 536, Class 1, NEC and other relevant industry standards). Extremely hazardous conditions can occur if the SED2 is not correctly grounded. Use only permanently wired input power connections. Only hard-wired input power connections are permissible. Use Class 1 60/75 copper wire only. The cross-section of the ground-bonding conductor must be at least equal to the input power cables. The following terminals can carry hazardous voltages even when the SED2 is not running: Input power terminals: L1, L2, L3 Motor terminals: U, V, W Link terminals: DC-, DC+/B+, DC/R+, B- (not for customer use) Connect input power to SED2 terminals L1, L2, and L3 (Figures 19 through 22).

48 SED2 VFD Startup, Operation, and Maintenance Manual Motor Cable Length Maximum motor cable length is 164 ft (50m). Motor cable length is given to ensure performance of only the SED2, not the suitability of the motor when connected to a SED2 at this distance.! 1. Never run control or drive input wires in the same conduit as the drive output wires. 2. Keep the distance from the drive to the motor as short as possible to maximize motor life. 4. If a disconnect is mounted on the load side of your drive, it is desirable to wire an auxiliary contact to the drive that will disable drive operation when the disconnect opens. (The wiring for this contact must not be run in the same conduit as the drive output wires). SED2 M VFD0014R2 3. If needed, use SBT-specified input line reactors to ensure a good impedance match with your drive. 5. Inverter duty motors are recommended. Install motors within their guidelines. Use dv/dt filters, output reactors, or other load conditioners as applicable or as specified by the motor manufacturer. Figure 23. Motor Cable Installation Notes. NOTE: If connecting multiple motors to one SED2, the total length of the individual motor cables must not exceed the maximum motor cable length. 38 Siemens Building Technologies, Inc.

49 Electrical Installation Motor Connection (Wye "Y"/Star or Delta Configuration) DANGER: Do not use the SED2 with a motor of higher nominal power rating than the SED2, or a nominal power less than half that of the SED2. Only operate the SED2 when the nominal current (P0305) is set to match motor rating continuous current. The motor nameplate indicates the required supply voltage and method of connection. In general, larger 400/690V motors connect in a delta ( ) configuration and smaller 230/400V motors connect in a Wye Y or star configuration (Figure 24). Connect motor wiring to SED2 terminals U, V, and W (Figures 19 through 22). MOTOR TERMINALS U1 V1 W1 U1 V1 W1 VFD0029R2 W2 U2 V2 W2 U2 V2 Wye "Y" Figure 24. Delta and Star (Wye, Y) Motor Connections.

50 SED2 VFD Startup, Operation, and Maintenance Manual Direction of Motor Rotation To change the direction of motor rotation, cross-connect two of the output conductors on the SED2 (Figure 25). This is the desired method for changing rotation. NOTE: The Reverse Output Phase Sequence parameter (P1820) can also reverse the direction of rotation. However, if the SED2 is reset to factory defaults, P1820 is reset to OFF. U U SED2 V V M W W U V VFD0030R1 SED2 V W U W M Figure 25.

51 Electrical Installation Motor Overload Protection WARNING: The SED2 is capable of providing internal motor overload protection in accordance with UL508C, Section 42. Accurately configure motor parameters for the motor overload protection to operate correctly. See Motor I 2 t Temperature Reaction parameter (P0610); I 2 t is On by default. Motor overload protection also can be provided using an external PTC temperature-thermistor sensor (disabled by default via Motor Temperature Sensor parameter (P0601)). During operation below nominal speed, the cooling effect of the fans mounted to the motor shaft is reduced. Therefore, most motors require de-rating if operated continuously at low frequencies. To ensure that motors are protected from overheating under these conditions, mount a PTC temperature-thermistor sensor to the motor and connect it to the control terminals of the SED2. NOTE: To enable the switch-off function with a PTC temperaturethermistor sensor, set Motor Temperature Sensor parameter (P0601) to 1 for PTC temperature-thermistor sensor. Use a shielded cable to connect the PTC temperature-thermistor sensor. 14 SED2 CONTROL TERMINALS VFD0031R1 15 Figure 26. External Motor Overload Protection. Siemens Building Technologies, Inc. 41

52 SED2 VFD Startup, Operation, and Maintenance Manual Connection of Multiple Motors The SED2 can control several motors in parallel as long as all of the motors have the same power rating. When multiple motors connect to the SED2 in parallel, the motors cannot operate individually. NOTES: SED2 5192Z10 1. When determining the required power, take into account the total current from all the motors (or the total of all ratings). 2.

59 Parameters Parameters Overview The SED2 uses parameters to define the required operating characteristics, such as motor data, ramp times, and maximum and minimum frequency. Users enter and modify the SED2 parameters using the Basic Operator Panel, the Advanced Operator Panel, or a serial interface. Each parameter consists of the letter "r" or "P", followed by four numbers, such as r0000 or P0010. The letter "r" identifies read-only parameters. The letter "P" identifies programmable parameters. Parameter Structure Figure 36 depicts the structure of the SED2 parameters. User Access Level parameter (P0003) selects the access level for using the parameters (1=standard, 2=extended, or 3=expert). The access level selected via parameter P0003 determines the number of parameters that are accessible by the user. For most applications, the Standard (1) and Extended (2) levels are sufficient. The factory default setting is P0003=1 (Standard). The filters of Parameter Filter parameter (P0004) categorize the parameters that are available via the access level according to functionality. The filters/categories enable a more focused operational approach. If parameter P0004=0 for no filter/category, then all parameters for a selected user access level are available. NOTE: Some parameters are intended for commissioning only and can be viewed as a function of this filter. In order to set these parameters, P0010 must be set to 1 (quick commissioning). Parameter Indexes Certain parameters have indexes. The indexes provide subsets of a particular parameter function and group together closely related parameter type information. The Parameter Reference Guide (Document Number ) lists any indexes associated with a parameter. Siemens Building Technologies, Inc. 49

61 SED2 Operator Panels SED2 Operator Panels Overview The SED2 includes the Basic Operator Panel (BOP) mounted as standard. An Advanced Operator Panel (AOP) is available as an option. Figure 37. Basic Operator Panel (BOP). Figure 38. Advanced Operator Panel (AOP). NOTES: 1. On initial startup, the SED2 display values alternate between 0.0 Hz (zero) and the speed it would be running if it were given a start command. 2. The BOP or AOP can connect to or disconnect from the SED2 without switching off power. Basic Operator Panel (BOP) The BOP provides access to the parameters of the SED2 and allows for application-specific settings of the SED2. The parameters and measured values are shown in a 5-digit LCD display. The BOP can mount directly onto the SED2 or, alternatively, it can mount into a control cabinet door using a special installation kit (SED2-DOOR-KIT1 or SED2-DOOR-KIT2). The BOP cannot store parameter data. Siemens Building Technologies, Inc. 51
